Definitions
- Tracheal intubation is a procedure involving the placement of a tube through the oral cavity, larynx, vocal cords and into the trachea.
- a laryngoscope is commonly used to view the glottis during placement of the endotracheal tube .
- the endotracheal tube often has a cuff that is inflated to form a seal with the interior walls of the trachea to prevent aspiration into the lungs.
- the present invention relates to systems and methods for endoscopic visualization of intubation using a guide device such as a catheter or endoscope for a procedure referred to herein as guided endotracheal intubation.
- a preferred embodiment of the invention includes the introduction of an imaging endoscope into the oropharynx of a patient's airway to provide direct visualization of the tracheal entry region.
- a guide device can be used to deliver an endotracheal tube that is placed into the trachea under direct visualization with the imaging endoscope.
- the guide device and/or the intubation tube can also be guided into position using the imaging endoscope at which point the guide device or endotracheal tube can be separated from the imaging endoscope for delivery of the endotracheal tube into the trachea.
- a smaller imaging endoscope and a small diameter guide device and endotracheal tube can be used for pediatric applications in which the critical anatomical features have smaller dimensions.
- a clear distal cap on the tip of the endoscope facilitates the visibility as it helps to keep tissue at a fixed distance from the lens instead of obstructing the view.
- Fig. 4 illustrates use of an endotracheal intubation endoscope system in accordance with a preferred embodiment of the invention.
- the endoscope needs to be withdrawn to separate the guide catheter from the endoscope before the catheter can be used to guide the endotracheal tube through the vocal cords into the airway.
- the endoscope needs to be reinserted alongside the guide catheter to observe the endotracheal intubation. In some patients this step may be omitted as the guide catheter can be used clinically to intubate the trachea blindly without endoscopic visualization.
- the observation of the intubation step provides an enhanced safety feature particularly for patients presenting more difficult issues for intubation.
- the length of the smaller endoscope can be about 200-400 mm longer than the large endoscope that can have a length 200-600 mm, for example, thus providing a smaller diameter endoscope that is longer than 500 mm, preferably about 700-800 mm.
- the diameter of the second smaller endoscope is preferably at least 1 mm smaller than the working channel 16, preferably about 2-3 mm in diameter.
- Existing pediatric bronchoscopes for example, have dimensions suitable for use.
- Illustrated in Fig. 6 is the insertion of catheter 104 through the proximal entry port 127 into the enclosed working channel 106.
- the endoscope is inserted over the tongue 117 to view the epiglottis 130, and the trachea 125.
- the epiglottis 130 can be lifted up with the guide device to display the vocal cords and the entry into the trachea.
- the smaller guide device 104 extending past vocal cords 139, comprises a small diameter endoscope having a separate processor housing 160 that can be connected to the proximal end.
- the smaller endoscope has a separate light source and imaging detector in housing 160 and can have a second control panel with separate switches to control imaging, suction and insufflation functions of endoscope 104.
- the working channel 106 has a panel 136 that moves to open the working channel so that the catheter or endoscope 104 can be removed and allow the tube 105 to be inserted into position alongside endoscope 118 as shown in Fig. 9.
- the optional cuff 203 can be situated between elements 209 and 210, for example, which can connect the endoscope to the endotracheal tube, i.e. the holders attach on first and second portions of the tube on different sides of the cuff.
- the holder elements are positioned along the steerable portion of the endoscope such that when the distal end of the endoscope is bent, the tube 202 has a bending region also bends to conform to the curved shape of the endoscope .
- a guide catheter 204 can also be used with the older elements 206, 209, 210 or a track facilitate positioning of tube 202.

Abstract
La présente invention porte sur un endoscope d'intubation endotrachéale guidée. Un cathéter de guidage est utilisé pour positionner un endoscope et un tube pour une intubation d'un patient. L'endoscope peut comprendre un dispositif d'orientation servant à orienter l'endoscope dans au moins deux directions, ainsi que des dispositifs d'aspiration, d'irrigation et de retrait destinés à maintenir un champ de vision dégagé.
